Tuning Rb25S For Eflex And E85 .

[Dose Pipe Sutututu]

I'll post up some updated ones tonight, added even more timing up top

Even better, will save me searching for them

here we go

• E85
• Hypergear SS2 0.82 Housing
• 45mm Turbosmart Hypergate External Gate off Turbo Housing
• Stock Manifold
• 1.6bar boost errrr day
• Made 343kW on Virtual Dyno (will hire a dyno one day when I have time and finalise the tune)

Hey i notice that you ramp your timing quite nicely... i found with the 0.82 rear i've been able to add more timing earlier to get up on power earlier.... i'll post a pic of my latest timing table on 98. i'm loving this thread i'm thinking of running e85, i'm all setup for it. I have a datalogit and powerfc as well.

as for the latency corrections i've found that the corrections if wrong a heard at idle, they are not precise from the injector manufacturer and its best to have a little play with the latency correction at idle and listen for it to be 'happy/smooth'.

Thanks for that Johny!

Here is my guestimate

Need to ramp my advance in quicker at low load

but ive not driven it yet

^ you should be able to run a bucket load more timing, also being a RB25DET the timing map has a hump before it decays timing in the vacuum area. This is evident in the factory Nistune, Haltech & PowerFC maps.

Other ECU manufacturers just put anything in there to make it run.. I based my map off the Haltech factory map to get the correct timing curve in the vacuum area and made my own tweaks to improve the torque & driveability.

Here's a factory Haltech Map for Unleaded Fuel (for E85 you could easily just add 5 degrees over the top and it would still be safe):

I do have a factory Haltech map there

Will side by side them this afternoon

[zebra]

well...she runs on e85 now

can't wait to get ot back on the road and start tuning

did you just blanket timing across the map? I started off with a decent 98 map then just went Ctrl + A and Page UP x5 LOL.. of course that was just to get started
